单词	ImaginaryUnit
释义	imaginary unit The imaginary unit $i:=\\sqrt{-1}$ . Any imaginary number $m$ may be written as $m=bi$ , $b\\in\\mathbb{R}$ . Any complex number $c\\in\\mathbb{C}$ may be written as $c=a+bi$ , $a,b\\in\\mathbb{R}$ . Note that there are two complex square roots of $-1$ (i.e. the two solutions to the equation $x^{2}+1=0$ in $\\mathbb{C}$ ), so there is always some ambiguity in which of these we choose to call “ $i$ ” and which we call “ $-i$ ”, though this has little bearing on any applications of complex numbers. In physics and some engineering fields, the symbol $j$ is used for the imaginary unit.
